In new street additions, Qitai built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Dabou built increasingly disconnected streets over time and Grabag built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Qitai grew more disconnected from 1975 through 1976-1990, then improved, while Dabou became progressively more disconnected and Grabag became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Qitai had a more sprawly network than Dabou in 1975 but the two have since reversed their relative ranking.
